Celtic winger Patrick Roberts is returning to parent club Manchester City for injury treatment.

Celtic boss Brendan Rodgers revealed Roberts could be out for up to three months with a hamstring problem.

Rodgers told BBC Radio Scotland: "Patrick is going to be out for a period of time. It could be anything up to three months.

"He is going back down the road to Manchester City to have another scan on it.

"It is just unfortunate. We will wait for the scan result, but he will certainly be out for the foreseeable future."
